THERMO-ELECTRIC GENERATOR.

` ra rented Nov. 3o, 1915 Application e March 12, 1914. Serial No. 824,183. l

To all /wzom it' may concern Be it known that we., Etienne GAIiRETsoN and Row/ino W. SonLnNnniz, citizens of the United States, residing at u'tl'alo, in the county et llrie and State of New York,- have invented new and useful Improvements in 'lhermo-lllectric Generators, of which the following is a specilication.

This invention relates to a thermo-electric generator which is more particularly designed tor use in therapeutic instruments in which the thermo-electric effect is produced by cool ing the instrument either by immersing the same in cold water or otherwise chilling the same.

lt the object of thisl invention to provide a, simple and eilicient device et this el aracter which is eomliact in construction, f hich quick in action and has a comparai veiy large out'iut for the size ofthe in ,une/nt. i lu theV accompanying drawings: Figure l is a hingitudiual sectional elevation of -a therapeutic instrument embodying our inventi on. li'

lines in Fig. 1.

` Similar characters of reference indicate :..oiri pending parts in both views.

In .ts general organization' our invention compri. is a plurality of thermo-pile couples oli peculiar construction which are so disposed that when the instrument containing 'the saine is chilled some parts of the thermopile couples `are also inimcriately chilled while other paris thereof are not immediately chilled, thereby producing a thermol elertme current due to this differential chillli il ig. '1% is a transverse section there- .oitaken in the coi-respondingly numbered detecting devices -lltorming part of our .invention are inc losed 1n the same casing o1" shell which contains he dianiagnetic bodies wherein diamaggnetism intensiiied for therapeutic pur-` poses. 'his casing .may lrie-'variously consti:'uf-tcd but as snown in the drawings. the `same comprises a sheet metaland two end caps orlheads 2, 3 ot metal applied to opposite ends of the body. f

VThethermo-pile embodying our invention is arranged in the central part of the casing and is constructed as follower- 4, 5 represent 'two partitions or transverse walls mounted in the front and rear parts of the cylindrical body ot thev casing and preterablyconstructed of iron. Arranged axially within the casing and connected at its front and Arear ends with the front and rear partitions is a` tie rod G which is also preferably constructed oi. iron. Upon this tie rod is arranged a tube or sleeve 7 of insuiating material such as rubber. 8 represents a plurality of disks, preferably of iron, forming one of the two kinds of thermo-electric elements and mounted 'side by side on the insulating sleeve yand -each provided at its margin with a reai'\i':1r'dly projecting annular flange. The several disks are insulated from each other by insulating disks 9 oi rubber.r liber or similar material extending from the insulating sleeve to the bore of the casing and each engaging on one side withthevuntianged side vof one of the ele-` ments 8 while its opposite side engages the flange of the edjacent element 8. The foremost element 8 is also insulated by a disk l0 of rubber or the like from the front partition l. vided' on diametrically opposite sides with curved openings 11, forming a hub 12 of comparatively large area at the center of the disk element, a rim 13 of comparatively lai-gc area,v and two radial arms 14.0f com- 'iaratively small area connecting diametri- :ally opposite sides of said hub with the rim, as shown in Fig. In its hub each of the' disk elements is provided witha notch @projecting fromits bore outwardly. l5
